is it normal not to have met your dc's nursery teacher?

that's it really. ds has just started morning nursery, we didn't bother with the afternoon sessions so this is his first time there. I haven't met his teacher and have only seen the teaching assistants in passing, I don't know any of their names. Should I try and introduce myself or is this normal?

They all line up outside and the teacher takes them in, when I pick him up they are sitting in the 'story corner' and get sent out one by one, the teacher stays in the classroom until everyone has left.

I'll phone next week. They know nothing about ds or me, it's very strange.

I think I may have missed out on the getting to know everyone bit by keeping ds at home last year. They seem to communicate by putting notes in pigeon holes. I got a message last week that Mrs X is ds's key worker. no idea who Mrs X is.
